ATTACHMENT FOR PLAN TERS.

Specification of Letters Patent.

Patented Jan. 13, 1914.

I To all whom itmay concern;

Be it known that I, 'Rnnonrn J. ALTGELT, of South Bend,in thecounty of St. Joseph and State of "Indiana, have invented certain newand useful Improvements in. Attach- ,ments' for Planters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will .enable others skilled in the art to which it :appertains to make and use the same.

This invention relates to improvements in attachments for planters and more particu larly to improved means for mounting covering disks in rear of the furrow-opening member,the object of my present invention being to so mount the supporting means for the covering disks that when one of the disks engages an obstruct-ion, it will rise and ride over the same without causing thelifting of the entire machine.

A further object is to so mount the covering disk axle that the same will havea swiveled support, whereby the two disks will be balanced against each other and the pressure on them from'below will be the same on one as on the other under normal conditions.

W lVith these and other objects in view, the

invention consists in certain novelfeatures of construction and combination of parts as hereinafter set forth and pointed out in the claims.

' In the accompanying drawings, Figure 1 is a rear elevation, showing my improvements; Fig. 2 is a side elevation, and Fig. 3 is a plan view. 1 represents a furrow opener or plow bottom which may be of the double mold-board type and provided with a suitable standard .or supporting means 2. Arms 3 are secured to the standard and embrace a seed tube 1. The rear ends of thearms 3 are provided with circular enlargements 5, having toothed outer faces to mesh with the toothed inner faces of enlargements 6 at the upper forward endsof arms 7. A bolt 8 passes through the disks 5 and 6 so as to hold the same locked together and retain the devices connected with the arms 7 at any desired vertical adjustment, as will he hereinafter made apparent. The arms 7 embrace one end of abar 9, which is bent to form an obtuse angle and projects downwardly and rear wardly from its connection with the plow standard. The. rear, normally horizontal portion 10 of bar Qcarries a bracket11, the central portion of which forms a sleeve 12 verse elongated slot 13, into which a pin 14.

on the portion 10 of bar 9 enters, to limit the rocking movement on the bracket and to prevent displacement of the latter longitudinally of the bar.

i As shown in Figs. 1 and 3, the bracket 11 is disposed transversely of the bar 9--10 and is provided with bearings 15 for a bent axle 16 on. which covering disks 17 are mounted. The axle 16 is so bent or curved as. to place the disks closer together below and behind rather than above and in front, in order to cause them to properly scrape the earth over the seed.

It is apparent that the covering disks may be adjusted vertically by means of the adjustable connecting means hereinbefore described, between the bar 9- 10 and the plow standard. By sw iveling bracket 10 to the bar 9-10, said bracket will be permitted to rock freely, so that when any obstruction,

such as a clod or stone, gets under one of the disks, thisdisk will be permitted to risea nd run over such obstruction without lifting the entire machine, the other disk being pressed deeper into the ground. With the use of my improvements, the two disks are balanced against each other and the pressure from belowyon them is always equal under normal conditions.

Having fully described my invention what I claim as new and desire to secure by Let ters-Patent, is

1. An attachment for planters, comprising a bar having an approximately horizontal portion, a bracket mounted tov a rock on said approximately horizontal portion of the bar, an axle secured to said brackettransversely of the bar, and disks mounted on said axle.

2. An attachment for planters, comprising a bar having an approximately horizontal portion, means for adjustably connecting the forward portion of the same with the planter in rear of the mounting of the furrow opening member thereof, a bracket mounted to rock on the approxi mately horizontal portion of said'bar, an axle secured to said bracket transversely of the bar, and covering disks mounted on said axle.

3. An attachment for planters, comprising a bar adapted for attachment to the planter in rear of the mounting of the furrow opening member thereof and having an approximately horizontal rear portion, a rocking bracket loosely mounted on the approximately horizontal rear portion of said bar, means for limiting the rocking movement of said bracket, covering disks disposed at an angle to each other, and mountings specification in the presence of two subscribmg Witnesses.
